New gear systems offer higher strength
The Davall Spiradrive is a right-angled/offset drive, consisting of a gear and pinion.
The reduction ratios can be increased significantly when mounting two reducers together to provide up to 9792:1 in a combination unit.
The core product is based around a simple, sealed for life, modular design, comprising of an innovative two piece aluminium casing, vacuum impregnated (to seal and protect) with Resinol RT, ground and case hardened alloy steel worm and a bronze alloy wheel.
The high-speed input shaft is supported with two oversized bearings, ideal for frequent start or reversing applications, whilst the slower speed shaft has oversized bearings to accommodate maximum output bore (or shaft) diameters, and the housing is sealed using high temperature nitrile seals.
Critical exterior surfaces are precision machined to enable a variety of mounting accessories to be attached, for example, either an IEC or NEMA C flange motor adapter, output torque arm.
The series has been developed to provide as many additional engineering features as might be required to design a drive, without the necessary delay and expense of a custom gearbox.
The product range is suitable for use in all applications, and is also available on request, either certified to ATEX Category 2 and ATEX Category 3 or with stainless steel components for food environments.
Designed primarily for the European market, metric configuration, there is the unusual option of standard products focused toward the significant North American market, based around imperial dimensions.
After market service is available through a global network of distributors and agents.
The series has been developed to replicate the critical dimensions of other popular gearboxes currently available.
